Musical Fidelity's x10-v3 tube output buffer?

I haven't heard it, but I did hear the predecessor of it, the x-10D. That served to mess the sound. You are better off with modifying your cd player, buying a better interconnect (harmonich technology interconnects are normally helping you getting a fuller sound), or some vibration control devices.

I would change the MF inergrated,I think that is your week link.I own and enjoy the MF A3 24 bit cd player.GREAT stand alone player.No complains about it's sound.Then again I have a stronger pre/power amp.Never auditioned the x-10 buffer.I wouldn't spend money on such device either.Upgrade to a line stage and perhaps a tubed power amp.Conrad Johnson Mv 55 is a great amp that I use with my set-up.
Hope that helps.

I too tried the original 10XD and found that it only "smoothed" (i.e., veiled) the sound in my system. Maybe the new version is better. Dave
